I'm trying to do call forward and the instruction says, I need to go to menu then options and I should see "call forward". However, I don't see that on my t-mobile Pearl. Does this mean I can't do call forward? :(

Use the *21*Number# then press the send (green button). Check the phone options to ensure that the forwarded number is in there. Then you can switch back to the voicemail number at any time. I've also rebooted my phone and the number that I to forward stayed in the menu.
